Cryptographic and Information-theoretic Security Capacities for General Arbitrarily Varying Wiretap Channels

Holger Boche, Ning Cai, Yiqi Chen +1

We compare the strong secrecy capacities of Arbitrarily Varying Wiretap Channels (AVWCs) and General Arbitrarily Varying Wiretap Channels (GAVWCs) with their capacities under seman…

Hierarchical Joint Source-Channel Coding with Constrained Information Leakage

Yiqi Chen, Holger Boche, Marc Geitz

This paper studies the hierarchical joint source-channel coding with information leakage constraint in the first-phase reconstruction and distortion constraints. The receiver's acc…

Lossy Source Coding with Broadcast Side Information

Yiqi Chen, Holger Boche, Marc Geitz

This paper considers the source coding problem with broadcast side information. The side information is sent to two receivers through a noisy broadcast channel. We provide an outer…

Robust Joint Message and State Transmission under Arbitrarily Varying Jamming

Yiqi Chen, Holger Boche

Joint message and state transmission under arbitrarily varying jamming is investigated in this paper. The problem is modeled as the transmission over a channel with random states w…

Variational Secret Common Randomness Extraction

Xinyang Li, Vlad C. Andrei, Peter J. Gu +3

This paper studies the problem of extracting common randomness (CR) or secret keys from correlated random sources observed by two legitimate parties, Alice and Bob, through public…

Integrated Sensing and Communication with Distributed Rate-Limited Helpers

Yiqi Chen, Holger Boche, Tobias J. Oechtering +1

This paper studies integrated sensing and communication (ISAC) systems with two rate-limited helpers who observe the channel state sequence and the feedback sequence, respectively.…
